WOOD-SCRAPER.

SPECIFICATION forming part of Letters Patent No. 778,849, dated January3, 1905. Application filed July 2'7, 1904. $eria1No. 218,415.

To all whom it may concern:

Be it known that I, JAMEs R. ELLIs, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented new and useful Improvements in Wood-Scrapers, of which thefollowing is a specification.

This invention is an improved wood-scraper for the use of carpenters andcabinet-makers, and is characterized particularly by improvement withrespect to the manner in which and the means by which the scraping-bladeis held in the stock and also by other improved details of construction,as will be more fully apparent from the following description.

In the accompanying drawings, Figure 1 is a front elevation of the tool.Fig. 2 is a rear elevation. Fig. 3 is a side elevation. Fig. 4 is asection on the line 4 4 of Figs. 1 and 2. Fig. 5 is a bottom plan view.

Referring specifically to the drawings, 6 indicates the back plate ofthe stock. This has a backwardly-extending foot 7, forming part of theface-plate of the tool. Said back plate also has at the top of its sideedges backwardlyprojecting ears 8 for attachment of the handles, whichare indicated at 9. These handles are detachably secured to the tool bymeans of a rod 10, which is fast to one handle and fits snugly throughholes in the ears and into the other handle, where its end is screwedinto the nut 11. To remove the handles, it is simply necessary tounscrew the same and pull the rod out of the ears. This is useful inpacking and carrying the tool. The front of the stock has two spacedupright portions 12, located at each side of the throat, which receivesthe blade 13. The uprights 12 are cast integrally with aforwardly-extending foot 14, which, with the foot 7, forms theface-plate of the tool, which slides over the work. This face ispreferably slightly convex, so that the knife will take better into thework.

The blade 13 is gripped at its side edges between the back plate 6 andthe uprights 12, and the foot 14 is cut away in front of the cuttingedges of the blade, as at 15. The

front and back pieces are held together and the side edges of the bladeclamped therebetween by means of screws 16, which extend through theback plate into the upright parts 12 of the front.

To hold the knife at adjustment, a screw 17 extends through the backplate at the middle thereof, with its point bearing against the bladenear the cutting edge. This screw serves to hold the blade atadjustment, and it also serves to slightly spring the knife forward atthe middle, and this action is permitted by the recess 15 in front ofthe knife. This action is advantageous, and it is to permit the samethat the screw 17 and the recess 15 are provided. The slight warp orcurve in the knife produced by the pressure of the screw 17 produces aslight curve of its cutting edge, so that said edge takes the wood at aslight angle on each side with respect to the middle,whereby an easy outis produced and chattering and stuttering is avoided. Furthermore, theout can be adjusted within certain limits without loosening the blade,since the more the blade is bent forward by the screw 17 the deeper thecut will be. Variation in the angle of the blade is not possible, sinceits side edges are firmly clamped. The top end of the blade projectsabove the stock, so that the tool can be turned over and the top endused, if desired, as in rough work. In close quarters the bandles can beremoved and the scraper used without the handles.

hat I claim as new, and desire to secure by Detters Patent, is-

1. The combination with a stock and faceplate, of a blade clamped at itsside edges in the stock and extending through a throat in theface-plate, the latter being recessed in front of the blade, andanadjusting-screw bearing laterally against the back face of the blade,opposite the recess, and arranged to warp or curve the blade.

2. The combination with front and back plates, the back plate havingears at the side edges thereof, and a blade clamped between the plates,of removable handles extending lateral] y from said edges, and ascrew-rod extending through the ears and connecting the handles.

3. The combination of front and back plates having respectivelyforwardly and rearwardly extending feet forming a face-plate, a blade Intestimony whereofIhave signed my name clamped at its side edges, only,between the to this specification in the presence of two subplates, thefront plate being recessed in front scribing Witnesses. of the blade,and an adjusting-screw extend- 5 ing through the back plate and bearingagainst Witnesses:
